I dont belive this, her mother is somehow the orchestrator that got the 3 to come to jeju and activate all that crap? What was terrorist man doing all this time, we saw they knew the island was going to explode. Why didnt they come with the space shuttle sooner and rescue the 3 is plan B was so important? Then our fmc sacrifices herself to kill her mother?? Like wat??? And exactly who tf was the mother in the first place to know all this plan b crap and wanting to destroy humanity etc????
